Patent number: 7510530Abstract: A pressing cuff presses a pressure sensor above an artery. The level of the pressure applied to the pressure sensor is changed while the pulse wave is measured based on information about the pressure from the pressure sensor. In order to adjust the level of the applied pressure using the pressure of gas in the pressing cuff, a three-port valve and a two-port valve are controlled so that the connection is changed to establish a state of holding the amount of the gas in the pressing cuff. Then, the state is changed to a state of isolating and discharging gas in which a part of the held gas is isolated from the remaining amount of the gas to be discharged. Then, the state is changed to the state of holding the remaining amount of gas in the pressing cuff.Type: GrantFiled: September 23, 2004Date of Patent: March 31, 2009Assignee: Omron Healthcare Co., Ltd.Inventors: Masao Hashimoto, Kazuhisa Tanabe, Hironori Satoh, Takashi Inagaki, Ryo Fukui

Publication number: 20090030329Abstract: A pulse wave measuring apparatus includes a pump (9) and a three-port valve (10). The pump (9) includes an exhaust port (91) and an intake port (92), and performs an operation to introduce gas in an air tube (32) from the intake port (92) and discharge the gas into an air tube (30) from the exhaust port (91). The three-port valve (10) performs an operation to selectively connect a cuff (13) to the exhaust port (91) of the pump (9) or connect the cuff (13) to the intake port (92) of the pump (9) and an exhaust valve (7). As a result of this operation, switching between a state that a gas flow path between the air tube (30) and an air tube (31) is established and a gas flow path between the air tube (31) and the air tube (32) is shut off and a state that the gas flow path between the air tube (31) and the air tube (32) is established and the gas flow path between the air tube (30) and the air tube (31) is shut off is made.Type: ApplicationFiled: May 22, 2006Publication date: January 29, 2009Applicant: OMRON HEALTHCARE Co., Ltd.Inventor: Kazuhisa Tanabe
